Non-Linear Socioeconomic Inequality in the Distribution of Food Outlets in Metropolitan Melbourne and Regional Victoria, Australia.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
issue addressedSocioeconomic disparities in food environments significantly impact diet quality and health outcomes, yet comparative evidence between metropolitan and regional areas remains limited. We examined spatial and temporal changes in food outlet availability in Victoria, Australia from 2019 to 2023.
methodsGeospatial data from OpenStreetMap was used to classify food outlets into healthy, less healthy, and unhealthy categories. Outlet densities were calculated within 500 m (walkable) and 2000 m (short driving) buffers from Statistical Area Level 1 centroids. Socioeconomic disparities were assessed using the Index of Relative Socio-economic Advantage and Disadvantage quintiles. Gini coefficients quantified inequality, while Kruskal-Wallis tests, Dunn's post hoc tests, and k-means clustering identified socio-spatial patterns.
resultsIn metropolitan Melbourne, both highly disadvantaged (quintile 1) and affluent areas (quintiles 4-5) had significantly higher densities of food outlets (e.g., 2.3 vs. 2.7 healthy outlets per 1000 people within 500 m in 2023), while mid-range socioeconomic areas (quintiles 2-3) had notably lower availability. Regional Victoria exhibited similar trends, with mid-range areas consistently underserved. From 2019 to 2023, Melbourne's Gini coefficients for healthy outlet access improved slightly (0.45-0.43), whereas regional areas worsened (0.52-0.55). Clustering revealed limited healthy food availability in disadvantaged rural clusters and high densities of unhealthy options in urban regional centres.
conclusionsFood outlet availability in Victoria shows distinct non-linear socioeconomic disparities, disproportionately disadvantaging mid-range socioeconomic areas. SO WHAT: Strategic urban planning and targeted policy interventions in underserved suburban and regional locations are essential for mitigating inequalities and promoting healthier communities.
